Hi,

this fixes a couple of oddities like slightly off DMA masks and add
support for hardware cursors on newer chips as well as support for the
sector layout bit in NVIDIA framebuffer modifiers.

The first patch in this set is a small helper that I think might be
useful to other drivers eventually, but if it isn't it's easily
something I can carry in the Tegra driver. It'd be great to get an
Acked-by on it from one of the drm-misc maintainers so that I can take
it through the Tegra tree.

James, I've added you on Cc on this one because it makes use of the
extended framebuffer modifiers that you introduced a while back to
support the sector layout mux on Tegra194. It'd be great to get your
thoughts on this just so this is used as expected.

Thanks,
Thierry
